DETAILED DESCRIPTION OF THE DRAWINGS

[0024] Referring to the drawings, wherein like reference numerals identify corresponding or similar elements throughout the several views, FIG. 1 illustrates a sanitization system 100 according to an embodiment of the present disclosure. The sanitization system 100 generally includes a container 102, which may also be referred to as a basin or a tub, that carries a cover 104 in a closed configuration, as illustrated. The container 102 includes a sanitization chamber (shown elsewhere) that receives and facilitates sanitizing one or more medical components (not shown—for example, one or more human breast milk pump components, baby bottles and reusable feeding equipment, one or more CPAP therapy components, or the like). More specifically, the sanitization chamber facilitates washing one or more medical devices by using a liquid (for example, water) and a detergent (for example, dish, sanitizing or anti-bacterial soap). The sanitization chamber also facilitates sanitizing one or more medical devices by exposing the devices to steam produced by delivering microwave energy to a liquid (for example, water) carried in the chamber. These aspects are described in further detail below.

[0025] The sanitization system 100 may be constructed of various microwave-safe materials, such as polymers. In some embodiments and as illustrated, the sanitization system 100 has a generally rectangular profile. Alternatively, the sanitization system 100 may have other a different profile, such as a circular profile. In some embodiments, the sanitization system 100 and the cover 104 have a height in a range of 4.75 in. to 5.25 in., more specifically about 4.9375 in., a length in a range of 11.0 in. to 14.0 in., more specifically about 13.75 in., and a width in a range of 8.0 in. to 9.75 in., more specifically about 9.5625 in.

[0026] FIG. 2 illustrates the container 102 of the sanitization system 100. The container 102 includes a base 106 and a plurality of walls 108 that define the sanitization chamber 110 and an upper opening 112 coupled the sanitization chamber 110. Although not shown, the container 102 may include feet extending downward from the base 106, preferably in the corners of the container walls so as to space the base 106 above the surface on which it is placed. this facilitates drying and helps limit sliding of the container which might otherwise happen if water is trapped between the base and the surface. The container 102 preferably has a maximum length and width that is similar to but slightly smaller than the cover 104. A sidewall that is slightly tapered facilitates stacking.

[0027] The sanitization chamber 110 also couples to one or more vents 114 formed in the walls 108 (illustratively, two vents 114). The vents 114 can be located in various positions in the sides, such as the corners as shown in FIG. 17. As described in further detail below, the vents 114 facilitate discharging steam from the sanitization chamber 110. In some embodiments, the vents 114 have a diameter of in a range of 1.0 in. to 1.5 in., more specifically about 1.25 in. The vents are designed to relieve pressure inside the chamber that is created by the steam during the sanitizing process (i.e., eh expansion of liquid to gas inside the container during sanitation. The vents are preferably located near the top of the walls 108 or in the cover 104. It is preferable to locate the vents 114 spaced laterally apart from handles 116 so as to reduce the likelihood of steam contacting a person's handles during movement of the container. The number and size are selected so as to maintain a sufficient volume of steam within the chamber in order to sufficiently sanitize the medical devices. In some embodiments, a sufficient volume of steam to sanitize the medical devices may be maintained by providing microwave energy for 3 minutes on a “high” power setting for a typical microwave (that is, the microwave having a power output of 800 W to 1100 W). It should be readily apparent that the amount of time to generate a sufficient volume of steam will vary depending on the container volume size, the power of the microwave and the venting. The walls 108 couple to one or more handles 116 (illustratively, two handles 116). The handles 116 are configured to be grasped by a user and facilitate carrying the sanitization system 100.

[0028] FIGS. 3-5 illustrate the cover 104 of the sanitization system 100. A lower side 118 of the cover 104 includes a protruding surface 120 that is sized to fit into the opening 112 of the container 102. The protruding surface 120 thereby facilitates positioning the cover 104 on the container 102 such that the cover 104 obscures the sanitization chamber 110. The cover 104 includes one or more handles 122 (illustratively, two handles 122). The handles 122 are configured to be grasped by a user and facilitate carrying the sanitization system 100. The handles 122 may be aligned with the handles 116 of the container 102 (shown elsewhere).

[0029] With continued reference to FIGS. 3-5, the protruding surface 120 on the lower side 118 of the cover 104 couples to a dryer rack 124. As described in further detail below, the dryer rack 124 may be used to support and facilitate drying medical devices after sanitization. As illustrated, the dryer rack 124 may be monolithically constructed with the cover 104. Alternatively, the dryer rack 124 may be detachably coupled to the cover 104. The dryer rack 124 is preferably configured to be positioned in the sanitization chamber 110 of the container 102 when the cover 104 is supported by the container 102 and obscures the sanitization chamber 110 (that is, when the closed configuration illustrated in FIG. 1).

[0030] The dryer rack 124 includes a plurality of supports for supporting medical devices. More specifically, the dryer rack 124 includes a plurality of fingers 126, a plurality of first nubs 128, and a plurality of second nubs 130. As illustrated, the fingers 126 may each include a short cylindrical portion 132 that carries elongated frustoconical portion 134. Alternatively, one or more of the fingers 126 may have different shapes. As illustrated, the first nubs 128 may each have a short cylindrical shape. Alternatively, one or more of the first nubs 128 may have different shapes. As illustrated, the first nubs 128 may be interposed between the fingers 126. Alternatively, the fingers 126 and the first nubs 128 may have different arrangements. As illustrated, each of the fingers 126 may have a first height, each of the first nubs 128 may have a second height, and the second height may be less than the first height. In some embodiments, the first height may be in a range of 1.0 in. to 1.5 in., more specifically about 1.25 in. Alternatively, one or more of the fingers 126 and/or one or more of the first nubs 128 may have different heights. As illustrated, the second nubs 130 are disposed aside the fingers 126 and the first nubs 128. As illustrated, the second nubs 130 may each have a double cylindrical shape, which may also be referred to as a “top hat” shape. As illustrated, each of the second nubs 130 may have a third height, and the third height may be less than the first height of the fingers 126 and greater than the second height of the first nubs 128. Alternatively, one or more of the second nubs 130 may have different heights.

[0031] The opposite side of the cover 104 preferably has one or more protruding ribs 105 that extend away from a top surface 107 of the cover. The ribs 105 are configured to space the top surface 107 apart, preferably about 0.5 inches or more, from any surface it is placed upon when it is used as a drying rack as discussed above.

[0032] The sanitization system 100 may also include a cleaning brush (not shown) to facilitate washing medical devices by using water and a detergent. The brush may be constructed of various appropriate materials, preferably microwavable-safe, such as polymers.

[0033] FIGS. 6-10 illustrate a method for using the sanitization system 100 to sanitize one or more medical devices 10 (illustratively, human breast milk pump components). Initially and as shown in FIG. 6, the cover 104 is removed from the container 102 (that is, the sanitization system 100 is configured in an open configuration) and medical devices 10 are positioned in the sanitization chamber 110 of the container 102. Next, the sanitization chamber 110 is partially filled with a liquid (not shown—for example, water). In some embodiments, the sanitization chamber 110 is partially filed with a volume of the liquid in a range of 1 oz. (30 mL) to 3 oz. (90 mL), more specifically a volume of the liquid of about 2 oz. (60 mL). The amount, of course, would vary depending on the volume of the chamber. Then and as shown in FIG. 7, the cover 104 is positioned on the container 102 such that the cover 104 obscures the sanitization chamber 110 (that is, the sanitization system 100 is reconfigured to the closed configuration). Additionally, the cover 104 is positioned such that the dryer rack 124 is positioned in the sanitization chamber 110 of the container 102 together with the medical devices 10. Next and as shown in FIG. 8, the sanitization system 100 is positioned in a microwave 20. Then the door 22 of the microwave 20 is closed, and the microwave 20 is energized to provide microwave energy to the sanitization system 100. More specifically, the microwave 20 may be energized in a range of 800 W to 1100 W for about 3 minutes. Alternatively, the microwave 20 may be energized at a different power level and/or for a different amount of time. Upon receiving microwave energy, the liquid in the sanitization chamber 110 of the container 102 is converted to steam, and the steam contacts and sanitizes the medical devices 10 in the sanitization chamber 110. Next, the sanitization system 100 is removed from the microwave 20. Then and as shown in FIGS. 9 and 10, the cover 104 is removed from the container 102 and positioned such that the dryer rack 124 faces generally upwardly. The medical devices 10 are removed from the sanitization chamber 110 of the container 102 and positioned on the dryer rack 124, specifically the plurality of fingers 126, the plurality of first nubs 128, and/or the plurality of second nubs 130, to facilitate drying the medical devices 10.

[0034] As described briefly above, the sanitization system 100 may facilitate washing one or more medical devices by using water and a detergent. More specifically, one or more medical devices may be positioned in the sanitization chamber of the container. Then, the sanitization chamber 110 of the container 102 may be partially filled with a liquid (for example, water) and a detergent (for example, dish soap). Next, the medical devices may be washed using the liquid, detergent, and the brush described above. The medical devices may then be rinsed and removed from the sanitization chamber 110 of the container 102 and positioned on the dryer rack 124 to dry. The sanitization system 100 may be used to wash the medical devices before and/or after sanitizing the medical devices by using the sanitization system 100 to provide steam as described above.

[0035] FIG. 11 illustrates a sanitization system 200 according to another embodiment of the present disclosure. The sanitization system 200 is similar to the sanitization system 100 described above. More specifically, the sanitization system 200 generally includes a container 202, which may also be referred to as a basin or a tub, that carries a cover 204 in a closed configuration, as illustrated. The container 202 includes a sanitization chamber that receives and facilitates sanitizing one or more medical components (for example, one or more human breast milk pump components, baby bottles and reusable feeding equipment, one or more CPAP therapy components, or the like). More specifically, the sanitization chamber facilitates washing one or more medical devices and exposing the devices to steam in similar manners to the sanitization system 100 described above.

[0036] The sanitization system 200 may be constructed of various microwave-safe materials, such as polymers. In some embodiments and as illustrated, the sanitization system 200 has a generally circular profile. Alternatively, the sanitization system 200 may have other a different profile, such as a rectangular profile.

[0037] FIG. 12 illustrates the sanitization system 200 in an open configuration in which the cover 204 is removed from the container 202. The container 202 is also illustrated as receiving medical devices 10 (illustratively, human breast milk pump components) in the sanitization chamber 210. The cover 204 is illustrated as including a dryer rack 224 and carrying a cleaning brush 250.

[0038] FIG. 13 illustrates the container 202 of the sanitization system 200. The container 202 is illustrated as receiving the medical devices 10 in the sanitization chamber 210. The container 202 includes a base 206 and a wall 208 that define the sanitization chamber 210 and an upper opening 212 coupled the sanitization chamber 210. The wall 208 couple to one or more handles 216 (illustratively, two handles 216). The handles 216 are configured to be grasped by a user and facilitate carrying the sanitization system 200. The wall 208 of the container 202 may be collapsible to facilitate storing the system 200 in a compact form.

[0039] FIG. 14 illustrates the cover 204 of the sanitization system 200. A lower side 218 of the cover 204 couples to the dryer rack 224, which may be used to support and facilitate drying medical devices after sanitization. The dryer rack 224 may be monolithically constructed with the cover 204. Alternatively, the dryer rack 224 may be detachably coupled to the cover 204. The dryer rack 224 includes a plurality of supports for supporting medical devices. More specifically, the dryer rack 224 includes a plurality of fingers 226, each of which may have an elongated cylindrical shape. Alternatively, one or more of the fingers 226 may have different shapes. The dryer rack 224 is configured to be positioned in the sanitization chamber 210 of the container 202 (both shown elsewhere) when the cover 204 is supported by the container 202 and obscures the sanitization chamber 210 (that is, when the closed configuration illustrated in FIG. 11). The cover 204 also includes one or more vents 214. The vents 214 facilitate discharging steam from the sanitization chamber 210 of the container 202 (both shown elsewhere).

[0040] FIG. 15 illustrates the sanitization system 200 in the open configuration and permitting the medical devices 10 to dry on the dryer rack 224 (for example, after using the system 200 to wash the medical devices 10 or expose the medical devices 10 to steam). FIG. 15 also illustrates the container 202 in a collapsed configuration.

[0041] FIG. 16 illustrates the cleaning brush 250 of the sanitization system 200. The cleaning brush 250 includes a flat bristle portion 252 and a tapered cleaning portion 254. The cleaning brush 250 may be constructed of various microwave-safe materials, such as polymers.

[0042] While he main intended use for the sanitization system is in hospital or clinical settings, it is also contemplated that the sanitization system can be used at an individual's home. In fact, it is contemplated that a patient will first use the sanitization system in a hospital or clinical office and then take the sanitization system home for continued home use.
